(So will ends per sleying repeat and dents per sleying repeat. You don&#8217;t need those for the calculator, but they&#8217;re useful if you want to know how to do the math on your own.)<\/p>\n\n\n\n<p>If you\u2019d like to understand how the calculator works or need help figuring out what the sleying pattern is, read on!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What sett will you get?<\/h3>\n\n\n\n<p>Here\u2019s the math you need to calculate EPI based on your choice of reed yourself, without the calculator:<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">ends \u00f7 dents x DPI = EPI<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Ends <\/strong>= the number of ends in the sleying repeat<\/li>\n\n\n\n<li><strong>Dents<\/strong> = the number of <em>dents<\/em> in the sleying repeat<\/li>\n\n\n\n<li><strong>DPI <\/strong>= the number of dents per inch (or cm) in your chosen reed<\/li>\n\n\n\n<li><strong>EPI <\/strong>= the number of ends per inch (or cm) you\u2019ll get with the given sleying pattern in your chosen reed.<\/li>\n<\/ul>\n\n\n\n<p>The last two things are pretty straightforward, but for the first two you need to know what the sleying repeat is. Note that even though the labels say &#8220;inch&#8221; the equation works for metric reeds too. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Sleying repeat<\/h3>\n\n\n\n<p>The sleying repeat is the repeating pattern in which we sley the dents of the reed.<\/p>\n\n\n\n<p>Normally choosing a sleying pattern has nothing to do with the threading and everything to do with sett. We know what sett we want and choose a sleying pattern to accomplish that.&nbsp;<\/p>\n\n\n\n<p>When a project recipe or sett chart tells you how to sley a reed, what it\u2019s giving you is the sleying repeat. It might look like 1-2-1-2 or 1|2|1|2, for example.&nbsp;<\/p>\n\n\n\n<p>Sometimes, though, we decide on a sleying pattern first and then want to know how many ends per inch or cm that turns into based on our choice of reed. Maybe we\u2019re weaving crammed and spaced stripes, or maybe we\u2019re using a threading that suggests a particular sleying pattern.&nbsp;<\/p>\n\n\n\n<p>Here\u2019s an example from Marguerite Davison\u2019s <a href=\"https:\/\/archive.org\/details\/handweaverspatte0000marg\"><em>A Handweaver\u2019s Pattern Book<\/em><\/a>, for instance:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"362\" src=\"https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-2-1024x362.png\" alt=\"\" class=\"wp-image-6756\" style=\"width:600px\" srcset=\"https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-2-1024x362.png 1024w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-2-300x106.png 300w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-2-768x272.png 768w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-2-1536x543.png 1536w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-2.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p>In this example, the vertical lines divide the threads into groups. Some of those groups have four ends, some have just one, and some of the groups are empty. <strong>Each group represents a single dent in the reed.<\/strong><\/p>\n\n\n\n<p><em>It\u2019s customary to read a threading from the tie-up out, so for this example I\u2019ll read both the threading and the sleying notations from right to left.<\/em><\/p>\n\n\n\n<p>The first group, at the right end of the threading, has 4 ends. The second group has just 1 end. The third group has 4 ends again. Then there\u2019s an empty dent. This part of the pattern goes 4-1-4-0. In the second half of the threading, the warp ends are on different shafts but <em>the sleying pattern stays the same<\/em>: 4-1-4-0. That means the sleying repeat is really just 4-1-4-0 over and over.&nbsp;<\/p>\n\n\n\n<p>To determine the number of <em>dents<\/em> in the sleying repeat, count the individual numbers, including the 0s. This example has four numbers and therefore four <em>dents<\/em> per sleying repeat.<\/p>\n\n\n\n<p>To determine the number of <em>ends<\/em> in the sleying repeat, add up all the numbers. This example has 4+1+4 = 9 total ends per sleying repeat.<\/p>\n\n\n\n<p>Now all we need is to decide what reed we\u2019ll be using and then plug the numbers into the equation<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">ends \u00f7 dents x DPI = EPI<\/p>\n\n\n\n<p>For example, if we were going to use a 12 dent reed, the equation would be&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">9 \u00f7 4 x 12 = 27 EPI<\/p>\n\n\n\n<p>If we used an 8 dent reed, we\u2019d get<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">9 \u00f7 4 x 8 = 18 EPI<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What reed should you use?<\/h3>\n\n\n\n<p><strong>Note: If a threading includes an unusual sleying pattern, that\u2019s often precisely because it weaves up better at something other than a normal, evenly spaced sett. Aiming for a specific sett is not necessarily your best bet.<br><br>That\u2019s good news, since reversing the equation to figure out the dents per inch or cm of the reed to use for an irregular sleying pattern is rarely going to give you nice, round numbers.<\/strong><\/p>\n\n\n\n<p>Now on to the math!<\/p>\n\n\n\n<p>If you want to know what reed to choose in order to get a particular sett when your sleying pattern is irregular, you need a slightly different equation:<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">dents \u00f7 ends x EPI = DPI<\/p>\n\n\n\n<p>Ends and dents are the same as before, they\u2019ve just swapped places. So have EPI and DPI.&nbsp;<\/p>\n\n\n\n<p>Suppose we wanted to use the sleying pattern from the example and achieve a sett of about 16 EPI.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\">4 \u00f7 9 x 16 = 7.111 DPI<\/p>\n\n\n\n<p>Chances are slim that you\u2019ve got a 7.1 dent reed kicking around, but an 8 dent reed will give you something not too far off 16 EPI.&nbsp;<\/p>\n\n\n\n<p>We calculated above that an 8 dent reed will actually give you 18 EPI, but because the threads are crammed and spaced, the fabric won\u2019t feel the same as if you\u2019d gotten 18 EPI with a regular sleying pattern like 3\/dent in a 6 DPI reed, or 1-2-1-2 in a 12.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example #2<\/h3>\n\n\n\n<p>Here\u2019s another example, also from <a href=\"https:\/\/archive.org\/details\/handweaverspatte0000marg\"><em>A Handweaver\u2019s Pattern Book<\/em><\/a>:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" width=\"1024\" height=\"523\" src=\"https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1024x523.png\" alt=\"\" class=\"wp-image-6754\" style=\"width:600px\" srcset=\"https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1024x523.png 1024w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-300x153.png 300w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-768x392.png 768w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1536x784.png 1536w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p>This draft shows two threading repeats. The one on the right is in Davison\u2019s usual threading notation. The one on the left is spaced out considerably to make room for the sleying notation, but the threading isn\u2019t any different.&nbsp;<\/p>\n\n\n\n<p>This time there aren\u2019t any vertical lines to show the groups (dents) but the idea is the same. Just like before&#8230;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Dents <\/strong>= the number of <em>groups<\/em> in the sleying repeat (that is, the number of symbols)<\/li>\n\n\n\n<li><strong>Ends <\/strong>= the total number of warp ends in the same section&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>If you\u2019re comfortable reading those numbers right from the diagram, great! If not, you might find it helpful to write them out the way we did before. I\u2019m going to write them out, partly because this draft has an error in the sleying notation that isn\u2019t obvious until you analyze it a bit.<\/p>\n\n\n\n<p><em>This time the tie-up is at the left, so I\u2019ll read the sleying pattern from the left end.<\/em><\/p>\n\n\n\n<p>This draft\u2019s sleying instructions say to put one thread in the first dent (o) then to leave a dent empty (x), then one thread in a dent (o), then leave a dent empty. So far, that\u2019s 1-0-1-0. Then there are three ends in a single dent followed by an empty dent. So the first half of the threading repeat is sleyed 1-0-1-0-3-0.&nbsp;<\/p>\n\n\n\n<p><strong>Notice that there&#8217;s an empty dent after every dent with threads in it.<\/strong> That is, every other number is a 0.<\/p>\n\n\n\n<p>The second half of the threading repeat has the same number of ends, so it&#8217;s logical to expect the second half of the sleying repeat to use the same number of dents and to follow the established pattern of an empty dent after each one that isn&#8217;t empty. &nbsp;<\/p>\n\n\n\n<p>That isn&#8217;t how it&#8217;s written, though: there\u2019s no empty dent indicated after the last group of three ends sleyed through a single dent. As it\u2019s written, the full sleying repeat is&#8230;&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center has-medium-font-size\">1-0-1-0-3-0-1-0-1-0-3 <\/p>\n\n\n\n<p>&#8230;and if we repeated that denting exactly as written for multiple threading repeats, we\u2019d get this:<\/p>\n\n\n\n<p class=\"has-text-align-center has-medium-font-size\">1-0-1-0-3-0-1-0-1-0-<strong>3-1<\/strong>-0-1-0-3-0-1-0-1-0-<strong>3-1<\/strong>-0-1-0-3-0-1-0-1-0-3<\/p>\n\n\n\n<p>The every-other-dent-is-empty pattern is interrupted at the end of each threading repeat.&nbsp;<\/p>\n\n\n\n<p>So which version is right? Normally we wouldn\u2019t know for sure whether there was an error in the notation or whether Davison really intended this interruption in the pattern. In this case, we can tell because she also tells us that the sleying pattern should give us 25 ends to 2 inches (or 12.5 EPI) in a 15 DPI reed.<\/p>\n\n\n\n<p>If you put the sleying repeat exactly as written into the calculator above, you\u2019ll see that a pattern of 1-0-1-0-3-0-1-0-1-0-3 in a 15 DPI reed actually results in a sett of 13.64 EPI, or about 27 ends in two inches, not 25. If you add the missing 0 at the end of the sleying repeat, though, you get exactly the 25 ends per two inches that she expected.<\/p>\n\n\n\n<p>The good news is that, with such an irregular denting, the difference between 25 and 27 ends per two inches probably won\u2019t be very significant, so you can use either version.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Example #3<\/h3>\n\n\n\n<p>Here\u2019s another example of a sleying repeat from <a href=\"https:\/\/archive.org\/details\/handweaverspatte0000marg\"><em>A Handweaver\u2019s Pattern Book<\/em><\/a>, and once again there\u2019s a missing o at the end:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img decoding=\"async\" width=\"1024\" height=\"413\" src=\"https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1-1024x413.png\" alt=\"\" class=\"wp-image-6755\" style=\"width:600px\" srcset=\"https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1-1024x413.png 1024w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1-300x121.png 300w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1-768x310.png 768w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1-1536x619.png 1536w, https:\/\/handweavingacademy.com\/wp-content\/uploads\/2024\/08\/image-1.png 1600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p>Can you figure out how many dents and ends per sleying repeat this draft recommends?<\/p>\n\n\n\n<p>As it\u2019s written, the sleying repeat for this pattern is 3-0-1-0-3-0-1, which is a total of 12 ends in seven dents.<\/p>\n\n\n\n<p>Once again, the intent is almost certainly that there be an empty dent after each non-empty dent. That means that the full repeat should actually be 3-0-1-0-3-0-1-0, which can be reduced to just 3-0-1-0. (You don\u2019t have to reduce the pattern. 6 ends in 4 dents is just the same ratio as 12 ends in 8 dents.)<\/p>\n\n\n\n<p>If I were going to sley this threading, I\u2019d use the second version, with an empty dent after each one that isn&#8217;t empty, which has a total of 6 ends in 4 dents (or 12 ends in 8 dents if it&#8217;s not reduced).<\/p>\n\n\n\n<p>Once you figure out what the sleying pattern is, you can use the equations above or <a href=\"#calculator\">jump back to the calculator<\/a> to determine EPI based on chosen reed, or DPI required to get a particular
